Clean and Verify extracted data

[ishanExtreme]

Overview

Since we are performing OCR on image and image can be blurred or some other noise in image can give unexpected results.

What needs to be done?

Perform verification on extracted data, whether it is in given range of category. For example in blood pressure instead of reading as '/' it is read as 1 which can give false result, for tempetature '.' is not read giving a result of original "29.7" to extracted "297", all these extracted categories require some pre-cleaning.
